Wildlife Spotting Masterclass
Maximize your snorkeling experience in South Korea by mastering the art of wildlife spotting. Here’s how to find the ‘Big Three’ marine species: turtles, manta rays, and reef sharks.
🦈 Turtles
How to Spot: Look for turtle nesting sites near sandy beaches during the early morning or late afternoon. Use a snorkel to glide quietly above coral reefs where they feed on seagrass.

Where to Go: Jeju Island, particularly around Hyeopjae Beach and the waters near Seongsan Ilchulbong.
🦈 Manta Rays
How to Spot: Dive at cleaning stations during high tide. Stay still and observe from a distance as they glide through the water, often near rocky outcrops.
Behavior Etiquette: Do not attempt to touch or block their path. Remain calm and keep your movements minimal to avoid startling them.
Where to Go: Busan, especially around the waters of Haeundae Beach and Gwangalli Beach.
🦈 Reef Sharks
How to Spot: Snorkel along drop-offs and coral reefs. Look for them during early morning hours when they are most active. Stay close to the reef structure for the best chance of spotting them.
Behavior Etiquette: Keep a safe distance and avoid splashing. Do not provoke or chase the sharks; observe their natural behavior.
Where to Go: Jeju Island, particularly around the waters of Seogwipo and the nearby reefs.
💡 Smart Insider Tip

- Use local tide charts to plan your snorkeling during optimal feeding times.
- Look for clusters of smaller fish, as they often signal the presence of larger predators like manta rays.
